Department of Transportation January 2008 – Federal Register Recent Federal Regulation Documents

The Federal Aviation Administration (FAA) announces its determination that the Noise Exposure Maps submitted by the City of Ocala for Ocala International Airport under the provisions of 49 U.S.C. 47501 et seq. (Aviation Safety and Noise Abatement Act) and 14 CFR Part 150 are in compliance with applicable requirements. The FAA also announces that it is reviewing a proposed Noise Compatibility Program that was submitted for Ocala International Airport under Part 150 in conjunction with the Noise Exposure Map, and that this program will be approved or disapproved on or before June 25, 2008.

The FHWA is issuing this notice to advise the public that an environmental impact statement (EIS) will be prepared for the construction of a new roadway located between County State Aid Highway (CSAH) 4/CSAH 133 in St. Joseph and Trunk Highway (TH) 15 in Waite Park, a distance of approximately 7 miles, in the St. Cloud Metropolitan Area, Stearns County, Minnesota.

The Federal pipeline safety laws allow a pipeline operator to request PHMSA to waive compliance with any part of the Federal pipeline safety regulations. We are publishing this notice to provide a list of requests we have received from pipeline operators seeking relief from compliance with certain pipeline safety regulations. This notice seeks public comment on these requests, including comments on any environmental impacts. In addition, this notice reminds the public that we have changed what we call a decision granting such a request to a special permit. At the conclusion of the comment period, PHMSA will evaluate each request individually to determine whether to grant a special permit or deny the request.

We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:

This notice solicits information and comments on proposed recommended practices for loading and unloading operations involving bulk packagings used to transport hazardous materials. In this notice, we summarize incident data related to bulk loading and unloading operations; discuss recommendations issued by the National Transportation Safety Board and the Chemical and Safety Hazard Investigation Board; provide an overview of current Federal regulations applicable to bulk loading and unloading operations; summarize the results of a public workshop we hosted earlier this year; and set forth proposed recommended practices for bulk loading and unloading operations. Based on information and comments received, we plan to consider strategies for enhancing the safety of bulk loading and unloading operations, including whether additional regulatory requirements may be necessary. In addition, we are soliciting comments on whether there are existing gaps and/or overlaps in regulations promulgated by PHMSA, OSHA, EPA and the USCG that adversely affect the safety of these operations, and how any identified gaps and/or overlaps in Federal regulations should be addressed.

The Maritime Administration is hereby giving notice that the closing date for filing applications to enroll in the Maintenance and Repair Reimbursement Pilot Program is extended until February 15, 2008. The notice announcing the initial application deadline was published in the Federal Register on July 2, 2007 (72 FR 36103). An extension to October 30, 2007 was previously published in the Federal Register on July 30, 2007 (72 FR 41581-01). A subsequent extension to December 30, 2007 was published in the Federal Register on October 30, 2007 (72 FR 61421-01).

This notice contains a summary of a petition seeking relief from specified requirements of 14 CFR.

This amendment adopts a new airworthiness directive (AD) for the specified Robinson Helicopter Company (Robinson) helicopters. This action requires a one-time visual inspection for skin separation along the leading edge of blade skin aft of the skin-to-spar bond line on the lower surface of each blade and in the tip cap area. This action also requires a ``tap test'' for detecting a separation or void in both bonded areas. This action also requires repainting any exposed area of the blades. If any separation or void is detected, replacing the blade before further flight is required. Thereafter, before each flight, this AD also requires checking for any exposed (bare metal) along the skin-to-spar bond line on the lower surface of each blade near the tip. If any bare metal is found, a mechanic must inspect the area. This amendment is prompted by 11 reports of blade debond, some occurring in flight causing the pilot to feel excessive vibrations and land, and some found during routine maintenance. The actions specified in this AD are intended to detect blade skin debond and to prevent blade failure and subsequent loss of control of the helicopter.

The Federal Highway Administration (FHWA) is issuing this notice to advise the public, affected Indian tribes and agencies that an environmental impact statement (EIS) will be prepared for the proposed development of a site to build pontoons that would be used to restore the function of the existing SR 520 Evergreen Point Bridge in case of catastrophic failure. The Washington State Department of Transportation (WSDOT) is a co-lead agency on the EIS. FHWA and WSDOT will prepare the EIS in accordance with the provisions of the National Environmental Policy Act (NEPA), the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU), and with Washington's State Environmental Policy Act (SEPA).

FMCSA previously announced its decision to renew the exemptions from the vision requirement in the Federal Motor Carrier Safety Regulations for 27 individuals. FMCSA has statutory authority to exempt individuals from the vision requirement if the exemptions granted will not compromise safety. The Agency has reviewed the comments submitted in response to the previous announcement and concluded that granting these exemptions will provide a level of safety that will be equivalent to, or greater than, the level of safety maintained without the exemptions for these commercial motor vehicle (CMV) drivers.

The FAA proposes to adopt a new airworthiness directive (AD) for various transport category airplanes. This proposed AD would require deactivation of Southeast Aero-Tek, Inc., auxiliary fuel tanks. This proposed AD results from fuel system reviews conducted by the manufacturer, which identified potential unsafe conditions for which the manufacturer has not provided corrective actions. We are proposing this AD to prevent the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.

The FAA is revising an earlier proposed airworthiness directive (AD) for certain Boeing Model 737-600, -700, -700C, -800 and -900 series airplanes. The original NPRM would have required sealing the fasteners on the front and rear spars inside the main fuel tank and on the lower panel of the center fuel tank, inspecting the wire bundle support installation in the equipment cooling system bays to identify the type of clamp installed and determine whether the Teflon sleeve is installed, and doing related corrective actions if necessary. The original NPRM resulted from a design review of the fuel tank systems. This action revises the compliance time for the corrective actions specified in the original NPRM. We are proposing this supplemental NPRM to prevent arcing at certain fuel tank fasteners in the event of a lightning strike or fault current event, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.

These special conditions are issued for the Boeing Model 787-8 airplane. This airplane will have novel or unusual design features when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. These novel or unusual design features are associated with connectivity of the passenger domain computer systems to the airplane critical systems and data networks. For these design features, the applicable airworthiness regulations do not contain adequate or appropriate safety standards for protection and security of airplane systems and data networks against unauthorized access. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing standards. Additional special conditions will be issued for other novel or unusual design features of the Boeing Model 787-8 airplanes.

This supplemental NPRM revises an earlier proposed airworthiness directive (AD), applicable to certain General Electric Company (GE) CF6-45 and CF6-50 series turbofan engines. That proposed AD would have required inspecting and reworking certain forward and aft centerbodies of the long fixed core exhaust nozzle (LFCEN) assembly. That proposed AD resulted from reports of separation of the forward and aft centerbodies of the LFCEN assembly due to high-imbalance engine conditions. This supplemental NPRM revises the proposed AD to add one engine model, and by replacing the LFCEN instead of repairing the centerbodies. This proposed AD results from the engine manufacturer issuing new service information. We are proposing this AD to prevent the forward and aft centerbody of the LFCEN assembly from separating, leading to additional damage to the airplane.

The FAA proposes to supersede an existing airworthiness directive (AD) for certain fuel injected reciprocating engines manufactured by Lycoming Engines. That AD currently requires inspection, and replacement if necessary, of externally mounted fuel injector fuel lines. This proposed AD would require the same actions but would add additional engine models, would clarify certain compliance time wording, and would exempt engines that have a Maintenance and Overhaul Manual with an Airworthiness Limitations Section that requires inspection, and replacement if necessary, of externally mounted fuel injector lines. This proposed AD results from Lycoming Engines revising their Mandatory Service Bulletin (MSB) to add new engine models requiring inspection, and from the need to clarify a repetitive inspection compliance time. We are proposing this AD to prevent failure of the fuel injector fuel lines that would allow fuel to spray into the engine compartment, resulting in an engine fire.

This amendment adopts a new airworthiness directive (AD) for Bell Helicopter Textron Canada (BHTC) Model 430 helicopters that requires replacing a certain servo actuator-to-actuator support attachment bolt (bolt) with an airworthy bolt. This action also requires establishing a retirement life for certain bolts and recording the retirement life on a component history card or equivalent record. This amendment is prompted by further evaluation of certain fatigue- critical parts, resulting in establishing a life limit of 5,000 hours for the affected bolts. The actions specified by this AD are intended to prevent fatigue failure of the bolt and subsequent loss of control of the helicopter.

The MUTCD (also referred to as ``the Manual'') is incorporated by our regulations, approved by the Federal Highway Administration, and recognized as the national standard for traffic control devices used on all public roads. The purpose of this notice of proposed amendments is to revise standards, guidance, options, and supporting information relating to the traffic control devices in all parts of the MUTCD. The proposed changes are intended to expedite traffic, promote uniformity, improve safety, and incorporate technology advances in traffic control device application. These proposed changes are being designated as the next edition of the MUTCD.
